Quality

Adjust the output quality (compression level) for lossy formats like JPEG and WebP.

Syntax

Command	Argument Format
quality	int (1–100)

Behavior

• Controls the trade-off between image quality and file size for supported formats (jpg, webp).
• Has no effect on lossless formats (like png or avif in lossless mode).
• Higher values produce larger files with better visual fidelity.
• Lower values reduce file size at the cost of detail and sharpness.

Accepted Range

• 1 — lowest quality, maximum compression
• 100 — best quality, minimal compression
• Default is typically format-specific if not explicitly set

Example

Set JPEG quality to 25:

Original image on the left, quality 25 on the right. Original is 4KB, quality 25 is 1KB.
